* PHI nodes must be the first thing in a basic block, all grouped together
* All basic blocks should only end with terminator insts, not contain them

This makes it much more useful for running benchmarks that are missing
prototypes for some functions.

char *malloc();
void free();
to forward declare malloc and free. Now we recognize and raise these forms

The new DEBUG(x) macro should be used instead of special purpose debug macros.

to certain classes. This is nice because it means that in header files we can
just declare a value, and still have that value be set based on a command-line
argument. The difference is now that the #include of CommandLine.h does not
need to go into the header file as well.

Also, added an option to specify which functions should be traced.
Particularly useful to reduce output volume in basic-block tracing.

-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect coloring for CC registers (both int and FP): interferences
were being completely ignored for int CC and were considered but no
spills were marked for fp CC!
Also some code improvements:
-- better interface to generating machine instr for common cases
(many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
one codegen phase to another (now used to pass information about
CALL/JMPLCALL operands from selection to register allocation)

"This testcase caused instcombine to fail because it got the same instruction on
it's worklist more than once (which is ok), but then deleted the instruction.
Since the inst stayed on the worklist, as soon as it came back up to be
processed, bad things happened, and opt asserted."

1. Avoid printing *(&globalvariable), instead print globalvariable alone
as a special case.
2. Inline subexpressions into expressions as much as legal that preserves
execution characteristics of expressions. Now we get nice (but
over-parenthesized, oh well) things like:
ltmp_428_7 = spec__putc(((unsigned char )((bsBuff) >> 24)), (bsStream));
instead of five seperate instructions (bsBuff & bsStream are globals).

* Fix loads & stores with zero indices
